wx: Reduce Opengl docs

Only use the first paragraph in the doc which contains an overview,
the result of the more detailed doc generated non valid xml, and
all math expressions was rendered poorly. Remove for now.

-%% the accumulation buffer. 
-%%
-%% `?GL_LOAD':  Similar to `?GL_ACCUM', except that the current value in the accumulation
-%% buffer is not used in the calculation of the new value. That is, the R, G, B, and A values
-%% from the currently selected buffer are divided by   2 n-1, multiplied by  `Value' ,
-%% and then stored in the corresponding accumulation buffer cell, overwriting the current
-%% value.

-%%
-%% `?GL_MULT':  Multiplies each R, G, B, and A in the accumulation buffer by  `Value' 
-%%  and returns the scaled component to its corresponding accumulation buffer location. 
-%%
-%% `?GL_RETURN':  Transfers accumulation buffer values to the color buffer or buffers
-%% currently selected for writing. Each R, G, B, and A component is multiplied by  `Value' 
-%% , then multiplied by   2 n-1, clamped to the range  [0 2 n-1], and stored in the corresponding

-%%  In RGBA mode, the lighted color of a vertex is the sum of the material emission intensity,

-%% vector from the vertex to the light source. The specular light source contribution is
-%% the product of the material specular reflectance, the light's specular intensity, and
-%% the dot product of the normalized vertex-to-eye and vertex-to-light vectors, raised to
-%% the power of the shininess of the material. All three light source contributions are attenuated

-%% 0 if they evaluate to a negative value. 
-%%
-%%  The alpha component of the resulting lighted color is set to the alpha value of the material
-%% diffuse reflectance. 
-%%
-%%  In color index mode, the value of the lighted index of a vertex ranges from the ambient

-%% values with unspecified mantissa and exponent sizes, scaled such that 0 represents zero

-%%
-%%  The pixel transfer operations performed on the four basic pixel types are as follows:

-%% `Color':  Each of the four color components is multiplied by a scale factor, then

-%% , then added to `?GL_BLUE_BIAS'; and the alpha component is multiplied by `?GL_ALPHA_SCALE'
-%% , then added to `?GL_ALPHA_BIAS'. After all four color components are scaled and
-%% biased, each is clamped to the range  [0 1]. All color, scale, and bias values are specified
-%% with ``gl:pixelTransfer''. 
-%%
-%%  If `?GL_MAP_COLOR' is true, each color component is scaled by the size of the corresponding

-%%  of many, but not all, of the parameters specified by these four commands. 
-%%
-%%  Data is read from  `Data'  as a sequence of signed or unsigned bytes, signed or unsigned
-%% shorts, signed or unsigned integers, or single-precision floating-point values, depending
-%% on  `Type' . When  `Type'  is one of `?GL_UNSIGNED_BYTE', `?GL_BYTE', `?GL_UNSIGNED_SHORT'
-%% , `?GL_SHORT', `?GL_UNSIGNED_INT', `?GL_INT', or `?GL_FLOAT' each
-%% of these bytes, shorts, integers, or floating-point values is interpreted as one color
-%% or depth component, or one index, depending on  `Format' . When  `Type'  is one of `?GL_UNSIGNED_BYTE_3_3_2'
-%% , `?GL_UNSIGNED_SHORT_5_6_5', `?GL_UNSIGNED_SHORT_4_4_4_4', `?GL_UNSIGNED_SHORT_5_5_5_1'
-%% , `?GL_UNSIGNED_INT_8_8_8_8', or `?GL_UNSIGNED_INT_10_10_10_2', each unsigned
-%% value is interpreted as containing all the components for a single pixel, with the color
-%% components arranged according to  `Format' . When  `Type'  is one of `?GL_UNSIGNED_BYTE_2_3_3_REV'
-%% , `?GL_UNSIGNED_SHORT_5_6_5_REV', `?GL_UNSIGNED_SHORT_4_4_4_4_REV', `?GL_UNSIGNED_SHORT_1_5_5_5_REV'
-%% , `?GL_UNSIGNED_INT_8_8_8_8_REV', or `?GL_UNSIGNED_INT_2_10_10_10_REV', each
-%% unsigned value is interpreted as containing all color components, specified by  `Format' 
-%% , for a single pixel in a reversed order. Indices are always treated individually. Color
-%% components are treated as groups of one, two, three, or four values, again based on  `Format' 
-%% . Both individual indices and groups of components are referred to as pixels. If  `Type' 
-%%  is `?GL_BITMAP', the data must be unsigned bytes, and  `Format'  must be either `?GL_COLOR_INDEX'
-%%  or `?GL_STENCIL_INDEX'. Each unsigned byte is treated as eight 1-bit pixels, with
-%% bit ordering determined by `?GL_UNPACK_LSB_FIRST' (see  {@link gl:pixelStoref/2} ). 
-%%
-%%  width×height pixels are read from memory, starting at location  `Data' . By default,
-%% these pixels are taken from adjacent memory locations, except that after all  `Width' 
-%% pixels are read, the read pointer is advanced to the next four-byte boundary. The four-byte
-%% row alignment is specified by  {@link gl:pixelStoref/2}  with argument `?GL_UNPACK_ALIGNMENT'
-%% , and it can be set to one, two, four, or eight bytes. Other pixel store parameters specify
-%% different read pointer advancements, both before the first pixel is read and after all  `Width' 
-%%  pixels are read. See the  {@link gl:pixelStoref/2}  reference page for details on these options.
-%% 
-%%
-%%  If a non-zero named buffer object is bound to the `?GL_PIXEL_UNPACK_BUFFER' target
-%%  (see  {@link gl:bindBuffer/2} ) while a block of pixels is specified,  `Data'  is treated
-%% as a byte offset into the buffer object's data store. 
-%%
-%%  The   width×height pixels that are read from memory are each operated on in the same
-%% way, based on the values of several parameters specified by  {@link gl:pixelTransferf/2} 
-%% and  {@link gl:pixelMapfv/3} . The details of these operations, as well as the target buffer
-%% into which the pixels are drawn, are specific to the format of the pixels, as specified
-%% by  `Format' .  `Format'  can assume one of 13 symbolic values: 
-%%
-%% `?GL_COLOR_INDEX':  Each pixel is a single value, a color index. It is converted
-%% to fixed-point format, with an unspecified number of bits to the right of the binary point,
-%% regardless of the memory data type. Floating-point values convert to true fixed-point
-%% values. Signed and unsigned integer data is converted with all fraction bits set to 0.
-%% Bitmap data convert to either 0 or 1. 
-%%
-%%  Each fixed-point index is then shifted left by `?GL_INDEX_SHIFT' bits and added to `?GL_INDEX_OFFSET'
-%% . If `?GL_INDEX_SHIFT' is negative, the shift is to the right. In either case, zero
-%% bits fill otherwise unspecified bit locations in the result. 
-%%
-%%  If the GL is in RGBA mode, the resulting index is converted to an RGBA pixel with the
-%% help of the `?GL_PIXEL_MAP_I_TO_R', `?GL_PIXEL_MAP_I_TO_G', `?GL_PIXEL_MAP_I_TO_B'
-%% , and `?GL_PIXEL_MAP_I_TO_A' tables. If the GL is in color index mode, and if `?GL_MAP_COLOR'
-%%  is true, the index is replaced with the value that it references in lookup table `?GL_PIXEL_MAP_I_TO_I'
-%% . Whether the lookup replacement of the index is done or not, the integer part of the
-%% index is then ANDed with   2 b-1, where   b is the number of bits in a color index buffer.
-%% 
-%%
-%%  The GL then converts the resulting indices or RGBA colors to fragments by attaching the
-%% current raster position `z' coordinate and texture coordinates to each pixel, then
-%% assigning   x and   y window coordinates to the   nth fragment such that  x n=x r+n% width
-%% 
-%%
-%%  y n=y r+|n/width|
-%%
-%%  where  (x r y r) is the current raster position. These pixel fragments are then treated just like
-%% the fragments generated by rasterizing points, lines, or polygons. Texture mapping, fog,
-%% and all the fragment operations are applied before the fragments are written to the frame
-%% buffer. 
-%%
-%% `?GL_STENCIL_INDEX':  Each pixel is a single value, a stencil index. It is converted
-%% to fixed-point format, with an unspecified number of bits to the right of the binary point,
-%% regardless of the memory data type. Floating-point values convert to true fixed-point
-%% values. Signed and unsigned integer data is converted with all fraction bits set to 0.
-%% Bitmap data convert to either 0 or 1. 
-%%
-%%  Each fixed-point index is then shifted left by `?GL_INDEX_SHIFT' bits, and added
-%% to `?GL_INDEX_OFFSET'. If `?GL_INDEX_SHIFT' is negative, the shift is to the
-%% right. In either case, zero bits fill otherwise unspecified bit locations in the result.
-%% If `?GL_MAP_STENCIL' is true, the index is replaced with the value that it references
-%% in lookup table `?GL_PIXEL_MAP_S_TO_S'. Whether the lookup replacement of the index
-%% is done or not, the integer part of the index is then ANDed with   2 b-1, where   b is
-%% the number of bits in the stencil buffer. The resulting stencil indices are then written
-%% to the stencil buffer such that the   nth index is written to location 
-%%
-%%  x n=x r+n% width
-%%
-%%  y n=y r+|n/width|
-%%
-%%  where  (x r y r) is the current raster position. Only the pixel ownership test, the scissor test,
-%% and the stencil writemask affect these write operations. 
-%%
-%% `?GL_DEPTH_COMPONENT':  Each pixel is a single-depth component. Floating-point data
-%% is converted directly to an internal floating-point format with unspecified precision.
-%% Signed integer data is mapped linearly to the internal floating-point format such that
-%% the most positive representable integer value maps to 1.0, and the most negative representable
-%% value maps to   -1.0. Unsigned integer data is mapped similarly: the largest integer value
-%% maps to 1.0, and 0 maps to 0.0. The resulting floating-point depth value is then multiplied
-%% by `?GL_DEPTH_SCALE' and added to `?GL_DEPTH_BIAS'. The result is clamped to
-%% the range  [0 1]. 
-%%
-%%  The GL then converts the resulting depth components to fragments by attaching the current
-%% raster position color or color index and texture coordinates to each pixel, then assigning
-%%   x and   y window coordinates to the   nth fragment such that 
-%%
-%%  x n=x r+n% width
-%%
-%%  y n=y r+|n/width|
-%%
-%%  where  (x r y r) is the current raster position. These pixel fragments are then treated just like
-%% the fragments generated by rasterizing points, lines, or polygons. Texture mapping, fog,
-%% and all the fragment operations are applied before the fragments are written to the frame
-%% buffer. 
-%%
-%% `?GL_RGBA'
-%%
-%% `?GL_BGRA':  Each pixel is a four-component group: For `?GL_RGBA', the red component
-%% is first, followed by green, followed by blue, followed by alpha; for `?GL_BGRA'
-%% the order is blue, green, red and then alpha. Floating-point values are converted directly
-%% to an internal floating-point format with unspecified precision. Signed integer values
-%% are mapped linearly to the internal floating-point format such that the most positive
-%% representable integer value maps to 1.0, and the most negative representable value maps
-%% to   -1.0. (Note that this mapping does not convert 0 precisely to 0.0.) Unsigned integer
-%% data is mapped similarly: The largest integer value maps to 1.0, and 0 maps to 0.0. The
-%% resulting floating-point color values are then multiplied by `?GL_c_SCALE' and added
-%% to `?GL_c_BIAS', where `c' is RED, GREEN, BLUE, and ALPHA for the respective
-%% color components. The results are clamped to the range  [0 1]. 
-%%
-%%  If `?GL_MAP_COLOR' is true, each color component is scaled by the size of lookup
-%% table `?GL_PIXEL_MAP_c_TO_c', then replaced by the value that it references in that
-%% table. `c' is R, G, B, or A respectively. 
-%%
-%%  The GL then converts the resulting RGBA colors to fragments by attaching the current
-%% raster position `z' coordinate and texture coordinates to each pixel, then assigning
-%%   x and   y window coordinates to the   nth fragment such that 
-%%
-%%  x n=x r+n% width
-%%
-%%  y n=y r+|n/width|
-%%
-%%  where  (x r y r) is the current raster position. These pixel fragments are then treated just like
-%% the fragments generated by rasterizing points, lines, or polygons. Texture mapping, fog,
-%% and all the fragment operations are applied before the fragments are written to the frame
-%% buffer. 
-%%
-%% `?GL_RED':  Each pixel is a single red component. This component is converted to
-%% the internal floating-point format in the same way the red component of an RGBA pixel
-%% is. It is then converted to an RGBA pixel with green and blue set to 0, and alpha set
-%% to 1. After this conversion, the pixel is treated as if it had been read as an RGBA pixel.
-%% 
-%%
-%% `?GL_GREEN':  Each pixel is a single green component. This component is converted
-%% to the internal floating-point format in the same way the green component of an RGBA pixel
-%% is. It is then converted to an RGBA pixel with red and blue set to 0, and alpha set to
-%% 1. After this conversion, the pixel is treated as if it had been read as an RGBA pixel. 
-%%
-%% `?GL_BLUE':  Each pixel is a single blue component. This component is converted to
-%% the internal floating-point format in the same way the blue component of an RGBA pixel
-%% is. It is then converted to an RGBA pixel with red and green set to 0, and alpha set to
-%% 1. After this conversion, the pixel is treated as if it had been read as an RGBA pixel. 
-%%
-%% `?GL_ALPHA':  Each pixel is a single alpha component. This component is converted
-%% to the internal floating-point format in the same way the alpha component of an RGBA pixel
-%% is. It is then converted to an RGBA pixel with red, green, and blue set to 0. After this
-%% conversion, the pixel is treated as if it had been read as an RGBA pixel. 
-%%
-%% `?GL_RGB'
-%%
-%% `?GL_BGR':  Each pixel is a three-component group: red first, followed by green,
-%% followed by blue; for `?GL_BGR', the first component is blue, followed by green and
-%% then red. Each component is converted to the internal floating-point format in the same
-%% way the red, green, and blue components of an RGBA pixel are. The color triple is converted
-%% to an RGBA pixel with alpha set to 1. After this conversion, the pixel is treated as if
-%% it had been read as an RGBA pixel. 
-%%
-%% `?GL_LUMINANCE':  Each pixel is a single luminance component. This component is converted
-%% to the internal floating-point format in the same way the red component of an RGBA pixel
-%% is. It is then converted to an RGBA pixel with red, green, and blue set to the converted
-%% luminance value, and alpha set to 1. After this conversion, the pixel is treated as if
-%% it had been read as an RGBA pixel. 
-%%
-%% `?GL_LUMINANCE_ALPHA':  Each pixel is a two-component group: luminance first, followed
-%% by alpha. The two components are converted to the internal floating-point format in the
-%% same way the red component of an RGBA pixel is. They are then converted to an RGBA pixel
-%% with red, green, and blue set to the converted luminance value, and alpha set to the converted
-%% alpha value. After this conversion, the pixel is treated as if it had been read as an

-%% the implementation-defined range [( -  bias max)(bias max)], where  bias max is the value of the implementation
-%% defined constant `?GL_MAX_TEXTURE_LOD_BIAS'. The initial value is 0.0. 
-%%
-%% `?GL_TEXTURE_MIN_FILTER':  The texture minifying function is used whenever the level-of-detail
-%% function used when sampling from the texture determines that the texture should be minified.
-%% There are six defined minifying functions. Two of them use either the nearest texture
-%% elements or a weighted average of multiple texture elements to compute the texture value.
-%% The other four use mipmaps. 
-%%
-%%  A mipmap is an ordered set of arrays representing the same image at progressively lower
-%% resolutions. If the texture has dimensions   2 n×2 m, there are  max(n m)+1 mipmaps. The first
-%% mipmap is the original texture, with dimensions   2 n×2 m. Each subsequent mipmap has
-%% dimensions   2(k-1)×2(l-1), where   2 k×2 l are the dimensions of the previous mipmap, until either
-%%   k=0 or   l=0. At that point, subsequent mipmaps have dimension   1×2(l-1) or   2(k-1)×1 until
-%% the final mipmap, which has dimension   1×1. To define the mipmaps, call  {@link gl:texImage1D/8} 
-%% ,  {@link gl:texImage2D/9} ,  {@link gl:texImage3D/10} ,  {@link gl:copyTexImage1D/7} , or  {@link gl:copyTexImage2D/8} 
-%%  with the `level' argument indicating the order of the mipmaps. Level 0 is the original
-%% texture; level   max(n m) is the final   1×1 mipmap. 
-%%
-%%  `Params'  supplies a function for minifying the texture as one of the following: 
-%%
-%% `?GL_NEAREST':  Returns the value of the texture element that is nearest (in Manhattan
-%% distance) to the specified texture coordinates. 
-%%
-%% `?GL_LINEAR':  Returns the weighted average of the four texture elements that are
-%% closest to the specified texture coordinates. These can include items wrapped or repeated
-%% from other parts of a texture, depending on the values of `?GL_TEXTURE_WRAP_S' and `?GL_TEXTURE_WRAP_T'
-%% , and on the exact mapping. 
-%%
-%% `?GL_NEAREST_MIPMAP_NEAREST':  Chooses the mipmap that most closely matches the size
-%% of the pixel being textured and uses the `?GL_NEAREST' criterion (the texture element
-%% closest to the specified texture coordinates) to produce a texture value. 
-%%
-%% `?GL_LINEAR_MIPMAP_NEAREST':  Chooses the mipmap that most closely matches the size
-%% of the pixel being textured and uses the `?GL_LINEAR' criterion (a weighted average
-%% of the four texture elements that are closest to the specified texture coordinates) to
-%% produce a texture value. 
-%%
-%% `?GL_NEAREST_MIPMAP_LINEAR':  Chooses the two mipmaps that most closely match the
-%% size of the pixel being textured and uses the `?GL_NEAREST' criterion (the texture
-%% element closest to the specified texture coordinates ) to produce a texture value from
-%% each mipmap. The final texture value is a weighted average of those two values. 
-%%
-%% `?GL_LINEAR_MIPMAP_LINEAR':  Chooses the two mipmaps that most closely match the
-%% size of the pixel being textured and uses the `?GL_LINEAR' criterion (a weighted
-%% average of the texture elements that are closest to the specified texture coordinates)
-%% to produce a texture value from each mipmap. The final texture value is a weighted average
-%% of those two values. 
-%%
-%%  As more texture elements are sampled in the minification process, fewer aliasing artifacts
-%% will be apparent. While the `?GL_NEAREST' and `?GL_LINEAR' minification functions
-%% can be faster than the other four, they sample only one or multiple texture elements to
-%% determine the texture value of the pixel being rendered and can produce moire patterns
-%% or ragged transitions. The initial value of `?GL_TEXTURE_MIN_FILTER' is `?GL_NEAREST_MIPMAP_LINEAR'
-%% . 
-%%
-%% 
-%%
-%% `?GL_TEXTURE_MAG_FILTER':  The texture magnification function is used whenever the
-%% level-of-detail function used when sampling from the texture determines that the texture
-%% should be magified. It sets the texture magnification function to either `?GL_NEAREST'
-%%  or `?GL_LINEAR' (see below). `?GL_NEAREST' is generally faster than `?GL_LINEAR'
-%% , but it can produce textured images with sharper edges because the transition between
-%% texture elements is not as smooth. The initial value of `?GL_TEXTURE_MAG_FILTER' is `?GL_LINEAR'
-%% . 
-%%
-%% `?GL_NEAREST':  Returns the value of the texture element that is nearest (in Manhattan

-%% 
-%%
-%% `?GL_TEXTURE_MAX_LOD':  Sets the maximum level-of-detail parameter. This floating-point

-%% 
-%%
-%% `?GL_TEXTURE_MAX_LEVEL':  Sets the index of the highest defined mipmap level. This

-%% , `?GL_GREEN', `?GL_BLUE', `?GL_ALPHA', `?GL_ZERO' and `?GL_ONE'.
-%% If `?GL_TEXTURE_SWIZZLE_R' is `?GL_RED', the value for  r will be taken from
-%% the first channel of the fetched texel. If `?GL_TEXTURE_SWIZZLE_R' is `?GL_GREEN'
-%% , the value for  r will be taken from the second channel of the fetched texel. If `?GL_TEXTURE_SWIZZLE_R'
-%%  is `?GL_BLUE', the value for  r will be taken from the third channel of the fetched

-%% from the fourth channel of the fetched texel. If `?GL_TEXTURE_SWIZZLE_R' is `?GL_ZERO'
-%% , the value for  r will be subtituted with  0.0. If `?GL_TEXTURE_SWIZZLE_R' is `?GL_ONE'
-%% , the value for  r will be subtituted with  1.0. The initial value is `?GL_RED'.

-%% 
-%%
-%% `?GL_TEXTURE_SWIZZLE_G':  Sets the swizzle that will be applied to the  g component
-%% of a texel before it is returned to the shader. Valid values for  `Param'  and their

-%% `?GL_TEXTURE_SWIZZLE_B':  Sets the swizzle that will be applied to the  b component

-%%
-%% `?GL_TEXTURE_SWIZZLE_A':  Sets the swizzle that will be applied to the  a component

-%% 
-%%
-%% `?GL_TEXTURE_SWIZZLE_RGBA':  Sets the swizzles that will be applied to the  r,  g, 
-%% b, and  a components of a texel before they are returned to the shader. Valid values for  `Params' 
-%%  and their effects are similar to those of `?GL_TEXTURE_SWIZZLE_R', except that all

-%%  is equivalent (assuming no errors are generated) to setting the parameters of each of `?GL_TEXTURE_SWIZZLE_R'
-%% , `?GL_TEXTURE_SWIZZLE_G', `?GL_TEXTURE_SWIZZLE_B', and `?GL_TEXTURE_SWIZZLE_A'
-%%  successively. 
-%%
-%% 
-%%
-%% `?GL_TEXTURE_WRAP_S':  Sets the wrap parameter for texture coordinate   s to either `?GL_CLAMP_TO_EDGE'
-%% , `?GL_CLAMP_TO_BORDER', `?GL_MIRRORED_REPEAT', or `?GL_REPEAT'. `?GL_CLAMP_TO_EDGE'
-%%  causes   s coordinates to be clamped to the range  [(1 2/N) 1-(1 2/N)], where   N is the size of the texture
-%% in the direction of clamping. `?GL_CLAMP_TO_BORDER' evaluates  s coordinates in a
-%% similar manner to `?GL_CLAMP_TO_EDGE'. However, in cases where clamping would have
-%% occurred in `?GL_CLAMP_TO_EDGE' mode, the fetched texel data is substituted with
-%% the values specified by `?GL_TEXTURE_BORDER_COLOR'. `?GL_REPEAT' causes the
-%% integer part of the   s coordinate to be ignored; the GL uses only the fractional part,
-%% thereby creating a repeating pattern. `?GL_MIRRORED_REPEAT' causes the   s coordinate
-%% to be set to the fractional part of the texture coordinate if the integer part of   s
-%% is even; if the integer part of   s is odd, then the   s texture coordinate is set to   1-
-%% frac(s), where   frac(s) represents the fractional part of  s. Initially, `?GL_TEXTURE_WRAP_S'
-%%  is set to `?GL_REPEAT'.

-%%
-%% Additional capitalized letters can indicate further alterations to the default behavior

-%% defined by the OpenGL specification. Signed values are understood to represent fixed-point

-%% `?GL_TEXTURE_MIN_FILTER':  The texture minifying function is used whenever the pixel
-%% being textured maps to an area greater than one texture element. There are six defined
-%% minifying functions. Two of them use the nearest one or nearest four texture elements
-%% to compute the texture value. The other four use mipmaps. 
-%%
-%%  A mipmap is an ordered set of arrays representing the same image at progressively lower
-%% resolutions. If the texture has dimensions   2 n×2 m, there are  max(n m)+1 mipmaps. The first
-%% mipmap is the original texture, with dimensions   2 n×2 m. Each subsequent mipmap has

-%%   k=0 or   l=0. At that point, subsequent mipmaps have dimension   1×2(l-1) or   2(k-1)×1 until
-%% the final mipmap, which has dimension   1×1. To define the mipmaps, call  {@link gl:texImage1D/8}

-%%  with the `level' argument indicating the order of the mipmaps. Level 0 is the original
-%% texture; level   max(n m) is the final   1×1 mipmap. 
-%%
-%%  `Params'  supplies a function for minifying the texture as one of the following: 
-%%
-%% `?GL_NEAREST':  Returns the value of the texture element that is nearest (in Manhattan
-%% distance) to the center of the pixel being textured. 
-%%
-%% `?GL_LINEAR':  Returns the weighted average of the four texture elements that are
-%% closest to the center of the pixel being textured. These can include border texture elements,
-%% depending on the values of `?GL_TEXTURE_WRAP_S' and `?GL_TEXTURE_WRAP_T', and
-%% on the exact mapping. 
-%%
-%% `?GL_NEAREST_MIPMAP_NEAREST':  Chooses the mipmap that most closely matches the size
-%% of the pixel being textured and uses the `?GL_NEAREST' criterion (the texture element
-%% nearest to the center of the pixel) to produce a texture value. 
-%%
-%% `?GL_LINEAR_MIPMAP_NEAREST':  Chooses the mipmap that most closely matches the size
-%% of the pixel being textured and uses the `?GL_LINEAR' criterion (a weighted average
-%% of the four texture elements that are closest to the center of the pixel) to produce a
-%% texture value. 
-%%
-%% `?GL_NEAREST_MIPMAP_LINEAR':  Chooses the two mipmaps that most closely match the
-%% size of the pixel being textured and uses the `?GL_NEAREST' criterion (the texture
-%% element nearest to the center of the pixel) to produce a texture value from each mipmap.
-%% The final texture value is a weighted average of those two values. 
-%%
-%% `?GL_LINEAR_MIPMAP_LINEAR':  Chooses the two mipmaps that most closely match the
-%% size of the pixel being textured and uses the `?GL_LINEAR' criterion (a weighted
-%% average of the four texture elements that are closest to the center of the pixel) to produce
-%% a texture value from each mipmap. The final texture value is a weighted average of those
-%% two values. 
-%%
-%%  As more texture elements are sampled in the minification process, fewer aliasing artifacts
-%% will be apparent. While the `?GL_NEAREST' and `?GL_LINEAR' minification functions
-%% can be faster than the other four, they sample only one or four texture elements to determine
-%% the texture value of the pixel being rendered and can produce moire patterns or ragged
-%% transitions. The initial value of `?GL_TEXTURE_MIN_FILTER' is `?GL_NEAREST_MIPMAP_LINEAR'
-%% . 
-%%
-%% `?GL_TEXTURE_MAG_FILTER':  The texture magnification function is used when the pixel
-%% being textured maps to an area less than or equal to one texture element. It sets the
-%% texture magnification function to either `?GL_NEAREST' or `?GL_LINEAR' (see
-%% below). `?GL_NEAREST' is generally faster than `?GL_LINEAR', but it can produce
-%% textured images with sharper edges because the transition between texture elements is
-%% not as smooth. The initial value of `?GL_TEXTURE_MAG_FILTER' is `?GL_LINEAR'. 
-%%
-%% `?GL_NEAREST':  Returns the value of the texture element that is nearest (in Manhattan
-%% distance) to the center of the pixel being textured. 
-%%
-%% `?GL_LINEAR':  Returns the weighted average of the four texture elements that are
-%% closest to the center of the pixel being textured. These can include border texture elements,

-%% on the exact mapping. 
-%%
-%% 
-%%
-%% `?GL_TEXTURE_MIN_LOD':  Sets the minimum level-of-detail parameter. This floating-point

-%% value is -1000. 
-%%
-%% 
-%%
-%% `?GL_TEXTURE_MAX_LOD':  Sets the maximum level-of-detail parameter. This floating-point
-%% value limits the selection of the lowest resolution mipmap (highest mipmap level). The
-%% initial value is 1000. 
-%%
-%% 
-%%
-%% `?GL_TEXTURE_WRAP_S':  Sets the wrap parameter for texture coordinate   s to either `?GL_CLAMP_TO_EDGE'
-%% , `?GL_MIRRORED_REPEAT', or `?GL_REPEAT'. `?GL_CLAMP_TO_BORDER' causes
-%% the   s coordinate to be clamped to the range [(-1 2/N) 1+(1 2/N)], where   N is the size of the texture in
-%% the direction of clamping.`?GL_CLAMP_TO_EDGE' causes   s coordinates to be clamped
-%% to the range  [(1 2/N) 1-(1 2/N)], where   N is the size of the texture in the direction of clamping. `?GL_REPEAT'
-%%  causes the integer part of the   s coordinate to be ignored; the GL uses only the fractional
-%% part, thereby creating a repeating pattern. `?GL_MIRRORED_REPEAT' causes the   s
-%% coordinate to be set to the fractional part of the texture coordinate if the integer part
-%% of   s is even; if the integer part of   s is odd, then the   s texture coordinate is

-%%
-%% `?GL_TEXTURE_BORDER_COLOR':  The data in  `Params'  specifies four values that
-%% define the border values that should be used for border texels. If a texel is sampled
-%% from the border of the texture, the values of `?GL_TEXTURE_BORDER_COLOR' are interpreted

-%%  is interpreted as a depth value. The initial value is (0.0,  0.0,  0.0,  0.0). 
-%%
-%% `?GL_TEXTURE_COMPARE_MODE':  Specifies the texture comparison mode for currently

-%%
-%% The commands ``gl:programUniform{1|2|3|4}{f|i|ui}v'' can be used to modify a single
-%% uniform variable or a uniform variable array. These commands pass a count and a pointer
-%% to the values to be loaded into a uniform variable or a uniform variable array. A count
-%% of 1 should be used if modifying the value of a single uniform variable, and a count of
-%% 1 or greater can be used to modify an entire array or part of an array. When loading `n'
-%%  elements starting at an arbitrary position `m' in a uniform variable array, elements
-%% `m' + `n' - 1 in the array will be replaced with the new values. If  `M'  +  `N' 
-%%  - 1 is larger than the size of the uniform variable array, values for all array elements
-%% beyond the end of the array will be ignored. The number specified in the name of the command
-%% indicates the number of components for each element in  `Value' , and it should match
-%% the number of components in the data type of the specified uniform variable (e.g., `1'
-%%  for float, int, bool; `2' for vec2, ivec2, bvec2, etc.). The data type specified
-%% in the name of the command must match the data type for the specified uniform variable
-%% as described previously for ``gl:programUniform{1|2|3|4}{f|i|ui}''.
-%%
-%% For uniform variable arrays, each element of the array is considered to be of the type
-%% indicated in the name of the command (e.g., ``gl:programUniform3f'' or ``gl:programUniform3fv''
-%%  can be used to load a uniform variable array of type vec3). The number of elements of
-%% the uniform variable array to be modified is specified by  `Count' 
-%%
-%% The commands ``gl:programUniformMatrix{2|3|4|2x3|3x2|2x4|4x2|3x4|4x3}fv''  are used
-%% to modify a matrix or an array of matrices. The numbers in the command name are interpreted
-%% as the dimensionality of the matrix. The number `2' indicates a 2 × 2 matrix (i.e.,
-%% 4 values), the number `3' indicates a 3 × 3 matrix (i.e., 9 values), and the number `4'
-%%  indicates a 4 × 4 matrix (i.e., 16 values). Non-square matrix dimensionality is explicit,
-%% with the first number representing the number of columns and the second number representing
-%% the number of rows. For example,  `2x4' indicates a 2 × 4 matrix with 2 columns and
-%% 4 rows (i.e., 8 values). If  `Transpose'  is `?GL_FALSE', each matrix is assumed
-%% to be supplied in column major order. If  `Transpose'  is `?GL_TRUE', each matrix
-%% is assumed to be supplied in row major order. The  `Count'  argument indicates the
-%% number of matrices to be passed. A count of 1 should be used if modifying the value of
-%% a single matrix, and a count greater than 1 can be used to modify an array of matrices.

-%% invocations because the value stored may remain in a cache local to the processor executing
-%% the store, or because data overwritten by the store is still in a cache elsewhere in the
-%% system. When ``gl:memoryBarrier'' is called, the GL flushes and/or invalidates any caches
-%% relevant to the operations specified by the  `Barriers'  parameter to ensure consistent
-%% ordering of operations across the barrier. 
-%%
-%%  To allow for independent shader invocations to communicate by reads and writes to a common

-%% Buffer object or texture image memory accessed through such variables may be cached only
-%% if caches are automatically updated due to stores issued by any other shader invocation.
-%% If the same address is accessed using both coherent and non-coherent variables, the accesses
-%% using variables declared as coherent will observe the results stored using coherent variables
-%% in other invocations. Using variables declared as "coherent" guarantees only that the
-%% results of stores will be immediately visible to shader invocations using similarly-declared
-%% variables; calling ``gl:memoryBarrier'' is required to ensure that the stores are visible
-%% to other operations. 
-%%
-%%  The following guidelines may be helpful in choosing when to use coherent memory accesses
-%% and when to use barriers. 
-%%
-%% Data that are read-only or constant may be accessed without using coherent variables or
-%% calling MemoryBarrier(). Updates to the read-only data via API calls such as BufferSubData
-%% will invalidate shader caches implicitly as required.
-%%
-%% Data that are shared between shader invocations at a fine granularity (e.g., written by
-%% one invocation, consumed by another invocation) should use coherent variables to read
-%% and write the shared data.
-%%
-%% Data written by one shader invocation and consumed by other shader invocations launched
-%% as a result of its execution ("dependent invocations") should use coherent variables in
-%% the producing shader invocation and call memoryBarrier() after the last write. The consuming
-%% shader invocation should also use coherent variables.
-%%
-%% Data written to image variables in one rendering pass and read by the shader in a later
